The Masahiro Historical series Katanas are all 100% hand forged samurai swords. Every sword in this series features an extremely sharp 1060 carbon steel blade that is differentially tempered. In addition, each Masahiro historical katana has a bronze tsuba which is antiqued to make it look like an authentic replica. The sageo and ito are woven from Japanese cotton and the tsuka is wrapped in authentic rayskin.
